Jesus accepted the mission to be born as a human, live several decades in this world without succumbing to the temptation of its deceptive will, then die as a human.
We cannot consider his death in isolation, without understanding what he endured in being born as a human, living a human lifespan and dying as all other mortals do. He did this to fulfill the Mysteries.
According to the texts bequeathed to us by the Hebrews, Sumerians and Babylonians, God manifested as a Patriarchal figure in the higher dimensions and breathed life into us as individual fields of force and energy. The Cosmic Source of All had already fostered the evolution of animal life in the atmospheric surface of this unique planet we call Earth.
There was a “Fall,” whereby we descended from the higher dimension to this lower plane and interbred with the hominids here. Then our souls became trapped in the cycles of physical life and death. The Fatherly Deity was displeased and decreed, “My Spirit will not contend with man forever, for he is mortal; his days will be a hundred and twenty years.” From then on we were stuck in this cycle of continuous deaths and re-births here on Earth.
God, in his manifestation as the Father of Humanity in the dimension above this one, also called the Celestial Plane, after intercession from enlightened beings such as Enoch, eventually consented to sire a Son through a Woman who was well prepared for the Mission by training with knowledgeable wise Women, and Jesus entered this world to make it possible for a Divine Being to be born, live to adulthood and die - as all humans do - without succumbing to the magnetic pull of the Terrestrial Plane. He broke the cycle.
We are all originally Divine Beings. It is up to us to accept this liberation from the Earthly cycle or, if we choose, stay attached to our existence on this plane. Jesus has unlocked our prison cells, but most of us prefer to stay inside them, waiting for something else to come along.
Christ knew in advance that the instrument of his execution - the Cross - would become his symbol. His reappearance on Sunday in a spiritual light-body shows us what lies ahead if we follow, as does his final Ascension. The Crucifix is not just about death: + is also a sign of Life, Light and Love.
